In Industrial accelerators Scan magnet is required to scan beam over a wide area of 1 meter to ensure uniform dose distribution on the products to be irradiated. Magnetic field of ~1.7 kG is required to deflect 10 MeV electron beam over the scan length. An AC, dipole magnet made up of 'Si steel' is developed to serve the purpose.

A triangular, bipolar, symmetrical current source is developed to energize the magnet. It is designed for an inductance of 429 mH and resistance of 4.8 Ohm. It operates at a scan frequency of 1-2 Hz. The equipment has been designed in 19"(W) 8U (H), 500mm (D) form factor.

Uniform distribution of electron beam on the product under irradiation, reduction in magnet size, power supply design is independent of L/R ratio of magnet. Power supply maintenance is easy due to usage of commercially available PLC controller.

Due to the closed loop current generator, the power supply design is independent of the L/R ratio of the magnet. Due to this, the physical size and weight of the scan magnet are reduced considerably. This scan magnet has overall dimensions of 300×240×50 mm3, and the weight is ~15kg.
